A Proton Pack was a piece of machinery in the movie series, The Ghostbusters. The machinery did not exist in real life and was made just for the movie as a source of fiction. It did not even possess any kind of powers. It can be quite easy to make a fake proton pack. You will need a big rectangle box and paint it black so that it looks like the main base unit of the proton pack. You can add a couple of wires, nuclear signs and other sorts of things so that it looks quite real. You can attach a pipe to the box so that it looks like a Proton Gun. The proton pack will look quite real if you copy it properly from the movie.
You can also get yourselves a jump suit similar to the ones in the movie and apply Ghostbusters patches that are quite easily available.
